Halogen-Carbon-Sulfur Compounds: Synthesis and Modes of Reactions of 4,5-Bis(trifluoromethyl)-1,3-dithiole Derivatives

The chemistry of the bis(trifluoromethyl)-1,3-dithiole system is thoroughly investigated starting from the 2-thione 6.By its oxidation the sulfine 2 and the ketone 7 are obtained.Further oxidation of 2 leads to the spiro compound 3.By chlorination of 6 th

An Unusual Synthesis of Tetrakis(trifluoromethyl)tetrathiafulvalene

Tetrakis(trifluoromethyl)tetrathiafulvalene (5) was formed in a phase-tranfer-catalyzed unusual one-step reaction by basic cleavage and subsequent alkylation of 1,3,4,6-tetrathiapentalene-2,5-dione (thiapendione) (1) with 2,3-dichlorohexafluoro-2-butene.As an example of the normal course of this reaction the synthesis of 4,5-(ethylenedithio)-1,3-dithiol-2-one (3) is described.
